Business-cycle Volatility and Long-run Growth: How Strong is the Relationship?
Abstract
This paper revisits the empirical relationship between business-cycle volatility and long-run
growth. The key contribution lies in controlling for fluctuations in the trend growth that also
accounts for enormous heterogeneity among countries in their long-run growth trajectories. The
results show that, after controlling for these fluctuations, there is no correlation between business
cycle volatility and growth. Otherwise, there would be a significantly negative correlation,
especially for developing countries, as documented in the literature. The results have
implications for stabilization policies, and also for cross-country growth regressions in that
ignoring heterogeneity among countries may lead to wrong conclusions.

Business-cycle Volatility and Long-run Growth: How Strong is the Relationship?
1. Introduction
This paper revisits the empirical relationship between business-cycle (BC) volatility1 and
long-run growth but the key contribution lies in controlling for fluctuations in the trend growth.
Addressing these fluctuations also accounts for enormous heterogeneity among countries in their
long-run growth trajectories. The main finding is that the significant volatility-growth correlation
(or arguably the causal effect of BC volatility on long-run growth) documented in the
literature—either negative or positive—disappears after controlling for such fluctuations.
Both the theoretical and empirical literature on the relationship between BC volatility and
long-run growth lack consensus. In the Schumpeterian (1939) tradition, where the mechanism is
“creative destruction,” the effect of business cycles on long-run growth is positive. For example,
Caballero and Hammour (1994) view recessions are a time of “cleansing,” when outdated or
unprofitable techniques and products are pruned out of the productive system. During recessions
firms also accumulate “organizational capital” (Hall, 1991) and/or reallocate labor (Davis and
Haltiwanger, 1990; 1992) that induce growth in the long run.
In contrast, a negative relationship between BC volatility and long-run growth is
predicted by endogenous growth theory based on the idea of learning-by-doing or demand spill-
overs (Arrow, 1962; Stadler, 1990; Martin and Rogers, 1997). For example, business cycles
create fluctuations in employment, and the unemployed lose their skills in recessions. Therefore,
in the presence of negative learning-by-doing, temporary shocks have negative impact on long-
run growth.2 However, in the models based on the opportunity cost arguments, the prediction of
the effect of business cycles on growth can be both positive and negative (Aghion and Saint-
Paul, 1998). For example, if the cost of productivity improvements positively depends on current
production, and this cost drops by more than its present discounted benefit in a recession, then
business cycles have a positive effect on growth. Saint-Paul (1997) provides evidence at the
1 This is volatility of growth rate as opposed to volatility of level of GDP. 2 Blackburn (1999) and Blackburn and Pelloni (2004) point out that the negative relationship based on learning-by-
doing may not hold in a stochastic growth model.

![Page 4: Business-cycle Volatility and Long-run Growth: How …epu/acegd2014/papers/...However, in the models based on the opportunity cost arguments, the prediction of the effect of business](https://reader033.fdocuments.us/reader033/viewer/2022042114/5e9106816f010029ec32bfb2/html5/thumbnails/4.jpg)
aggregate level in favor of this argument. On the other hand, if the cost of productivity-
enhancing activities does not depend on current production, the conclusion of the model reverses
and recession have a negative long-run effect.
Given the lack of consensus on the theoretical predictions, the burden is on the empirical
side to establish the actual relationship. But empirical evidence also lacks consensus. For
example, Kormendi and Meguire (1985), Grier and Tullock (1989) and Stastny and Zagler
(2007) find a positive correlation between business cycles and long-run growth. In contrast,
Ramey and Ramey (1995), Martin and Rogers (2000), Kneller and Young (2001), Fatás (2002),
Döpke (2004) and Rafferty (2005) find a negative correlation. The observed relationship also
varies across country groups. For example, Martin and Rogers (2000) find a negative
relationship for the industrialized countries but insignificant relationship for the non-
industrialized countries. They attribute learning-by-doing as a mechanism that may not be at
work for the latter group of countries.3 Imbs (2007) finds volatility and growth to be positively
related at the sectoral level but negatively related at the aggregate level. Furthermore, it has not
been established satisfactorily whether the observed relationship is a correlation or a causal
effect of BC volatility on long-run growth. It is important to point out that the theoretical models
implicitly argue for an effect of BC volatility on future growth, while the empirical studies have
tested a contemporaneous correlation.
Notwithstanding a large body of empirical research on the volatility-growth relationship,
the literature has categorically ignored fluctuations in the trend growth. The following examples
will illuminate the danger of ignoring such fluctuations in estimation. Consider two countries—A
and B—with identical average growth performances over 20 years (for simplicity consider
arithmetic average). Suppose that the annual growth rate in country A alternated every year
between 2% and -2% (i.e., 2, -2, 2, -2, ---- 2, and -2), while that in country B was 2% in the first
10 years and -2% in the last 10 years. Both countries have the same average growth rate (zero)
and volatility (measured by the standard deviation which is 2.052) but patterns of the trend
growth in these two countries are clearly different. The trend growth rate in country B is seven
times as volatile as in country A (the standard deviation of the trend growth calculated using the
3 Young (1993) also argues that growth will be driven by learning-by-doing only at relatively high levels of
development.

Hodrick-Prescott (H-P) filter is 0.270 and 1.908 in country A and B, respectively). On the other
hand, BC volatility (measured by the standard deviation of the cyclical component calculated
using the same filter) in country A is 3.5 times as large as in country B (2.001 and 0.567,
respectively). Suppose, there is another country C that experienced a -2% growth rate in the first
12 years, zero in next 2 years and 4% in the last 6 years. Although average growth in country C
is also zero and its BC volatility (0.573) is similar to that in country B, volatility of its trend
growth (2.62) is greater than that in both A and B. In Section 3, we provide similar examples
observed in the data.
The above examples illustrate that many dissimilar growth trajectories that differ in terms
of fluctuations in the trend growth can lead to the same average growth rate. By ignoring these
fluctuations, the literature also fails to address the enormous heterogeneity among countries. In
this paper, we address these fluctuations by the standard deviation of the trend (long-run) growth
rate calculated by the low-pass filter (we refer it to long-run (LR) volatility). The reason for
controlling LR volatility in estimation can also be understood from the following volatility
decomposition. Given that there are enormous transitory (cyclical) variations around the trend
growth for many countries and that the trend growth per se is also volatile, per capita real GDP
growth rate ( ,y tg ) can be written as the sum of two orthogonal terms, its business-cycle ( ,BCy tg )
and long-run components ( ,LRy tg ): , , ,
BC LRy t y t y tg g g= + .4 Its variance is then decomposed as
, , ,Var( ) Var( ) Var( )BC LRy t y t y tg g g= + .
We use this spectral relation to explore the volatility-growth relationship at the cross-
country level. Our main source of data is the PWT 8.0. We choose the 1960-2007 period because
of unavailability of data for control variables for periods earlier than 1960 and to ensure that our
results are not influenced by the recent global financial crises that started in 2008. We also
estimate for the 1960-1980, 1970-2007 and 1980-2007 sub-periods, and disaggregating by the
intensity of BC volatility and country income groups. To verify the results from an alternative
dataset and different time periods, we perform a separate analysis for the 1878-2010 period using
4 Romer (2012, p. 136) stresses that statistical tests do not determine whether growth rate is stationary or
nonstationary; rather they suggest that “there are highly transitory movements in growth that are large relative to any
long-lasting movements that may be present.” The question of stationarity is also economically unimportant.

![Page 6: Business-cycle Volatility and Long-run Growth: How …epu/acegd2014/papers/...However, in the models based on the opportunity cost arguments, the prediction of the effect of business](https://reader033.fdocuments.us/reader033/viewer/2022042114/5e9106816f010029ec32bfb2/html5/thumbnails/6.jpg)
the historical time series compiled by Angus Maddison for a relatively small number of
countries. As an additional robustness check, we replicate Ramey and Ramey (1995, AER) using
their data.
The BC and LR volatility are calculated as the standard deviation of the cyclical and
long-run components of (annual) per capita real GDP growth rate, respectively. We extract these
two components employing the Baxter-King (B-K) (1999) filter at the business-cycle and low
frequencies, respectively. We choose a window of 3 years, and critical periodicities (inversely
related to frequencies) of 2 and 8 years for the business cycle, and 8 years and above for the
long-run. We estimate both cross-section and panel data. The cross-section data is constructed by
taking average and calculating standard deviation of the relevant variables over the sample
period. To construct the panel data, non-overlapping average over 7 years has been taken for the
annual growth rate and other series. We show that averaging over 7 years performs better in
terms of reweighting the variances of the raw series across low frequencies than averaging over 5
years as commonly done in the cross-country growth literature. BC and LR volatility have been
calculated as the standard deviation of the respective filtered growth rates over the same interval
but the filter has been modified as one-sided using only lag values so that an artificial reverse
causality from growth to volatility is not generated.
We test both the contemporaneous correlation between BC volatility and growth
following the empirical literature, and the neglected theoretical prediction of the effect of BC
volatility in the previous period on current growth. We find that there is no correlation between
BC volatility and growth. The result is robust in both cross-sectional and panel estimations, and
in both the PWT and Angus Madison datasets. But if LR volatility is incorrectly excluded from
the regression, the correlation becomes significantly negative, especially for developing
countries in the post-1970 period. There is also no effect of BC volatility in the previous period
on current growth. The direction of bias in the coefficient on BC volatility depends on the
correlation between growth rate and LR volatility excluded in the regression. Our measure of LR
volatility can also be interpreted as persistence in volatility. We find that persistence in volatility
has a negative association with growth for developing countries in the post-1970 period.
Our results have important implications for stabilization policies in light of the recent
global financial crises that caused a prolonged recession and depressed many developed
economies enough to lower the trend growth. However, such contractions are more frequent in

developing than developed countries. Berg, Ostry and Zettelmeyer (2012) show that inequality of
the income distribution, lack of democratic institutions and macroeconomic instability are some
factors that cause shorter growth spells (prolonged and more frequent recessions). Mallick
(2014) shows that terms-of-trade volatility and financial underdevelopment cause persistent
growth volatility. But these characteristics may also be symptoms as well as propagation
mechanisms of volatility persistence. Understanding volatility persistence is crucial for designing
stabilization policies but is an under-researched area, even in the context of developed countries.
The rest of the paper proceeds as follows. Section 2 discusses the data including
construction of both BC and LR volatility. Section 3 motivates the paper by presenting examples
of heterogeneity observed across countries in terms of their growth trajectories. This section also
presents some key descriptive statistics. The estimation strategy is explained in Section 4. The
results are discussed in Section 5. Section 6 compares the relative importance of volatility and its
persistence in explaining growth. Section 7 compares the paper’s contribution in the cross-
country macroeconomic literature regarding volatility persistence. Finally, Section 8 concludes.
2. Data
In this section we explain the data used in our empirical analysis including construction
of BC and LR volatility.
The main source of data is the PWT 8.0. Average per capita growth rate and volatility
have been calculated from the RGDPNA series (the real GDP at constant national prices), which
is recommended to compare growth rates across time and countries (Feenstra, Inklaar and
Timmer, 2013, Table 5 in p. 30). Per capita real GDP (Y) is calculated by dividing RGDPNA by
population (POP). Annual growth rate is calculated as the log difference: -1ln( / )t t tdy Y Y= .
The BC and LR volatility have been calculated as the standard deviation of the cyclical
and long-run components of tdy , respectively, extracted employing the B-K filter.5 A window of
5 Levy and Dezhbakhsh (2003) and Mallick (2014) calculate BC and LR volatility using the spectral method by
integrating the spectrum over the relevant frequency ranges. However, this method requires relatively long time
series, so that it cannot be employed at our panel data analysis. Fatás (2000a, 2000b), Levy and Dezhbakhsh (2003),
Aguiar and Gopinath (2007) and Nakamura, Sergeyev and Steinsson (2012) employ the Cochrane’s (1988) variance
ratio to calculate LR volatility but this method cannot be used to calculate BC volatility. Another alternative can be
unobserved component (UC) model. For example, Stock and Watson (2007) and Ascari and Sbordone (2014)

![Page 8: Business-cycle Volatility and Long-run Growth: How …epu/acegd2014/papers/...However, in the models based on the opportunity cost arguments, the prediction of the effect of business](https://reader033.fdocuments.us/reader033/viewer/2022042114/5e9106816f010029ec32bfb2/html5/thumbnails/8.jpg)
3 years, and critical periodicities of 2 and 8 years for cyclical components (band-pass filter), and
8 years and above for long-run components or equivalently low frequency components (low-pass
filter) have been chosen.6 The main purpose of a filter is to extract the cyclical components of a
series, and the long-run components are then recovered as the residual. But we extract the long-
run components using the low-pass filter assuming that per capita real GDP growth is stationary.
Average growth rate (Δy) is the average of tdy . For the cross-section data, we take
average of tdy , and calculate the standard deviation of the filtered series over the entire sample
period. The panel data has been constructed by non-overlapping averaging over 7 years.
Volatility calculated as the standard deviation of the filtered growth series may be problematic
for our purpose because the B-K filter is based on a (symmetric) moving average of the lead and
lag values. As a result, volatility for a particular interval also incorporates information about
growth of the preceding interval, which artificially generates a reverse causality from growth to
volatility. To avoid this problem, we transform the growth series by one-sided filter using only
the lag values, and calculate the standard deviation of this modified filtered series.
For initial level of GDP, we use the CGDPe series (expenditure-side real GDP at current
PPPs in million 2005 US$ that compares relative living standards across countries at a single
point in time), as recommended by Feenstra, Inklaar and Timmer (2013). Terms of trade (ToT) is
estimate the time varying volatility of the trend and cyclical components of inflation for the USA. This method is
not suitable at the cross-country level because iteration does not converge for many countries, especially the
developing ones.
6 Comin and Gertler (2006), Comin (2009) and Comin et al. (2014) employ a non-standard definition of long-run in
terms of the periodicity of 200 quarters and above. They refer to the periodicities between 2 and 200 quarters as the
medium-term business cycle of which periodicities between 2 and 32 quarters as the high-frequency component of
the medium-term (the standard business cycles), and frequencies between 32 and 200 quarters as the medium-
frequency component of the medium-term. The authors also show that high and medium term fluctuations of GDP
are connected. Our definition of long-run periodicities of 8 years (32 quarters) and above includes their medium-
frequency components, and we emphasize the importance of correlation between growth volatility at business cycle
and long-run periodicities. Chirinko and Mallick (2014) demonstrate in a different context that a critical periodicity
of 8 years sufficiently captures the long-run information and gain from further increasing this cut-off is negligible.

calculated as the ratio of export to import price (PL_X / PL_M). Investment and government
expenditure shares of GDP are the CSH_I and CSH_G series, respectively.
Openness is the sum of exports and imports as a share of GDP at the current price and the
data is obtained from the PWT 7.1 (this data is not available in the PWT 8.0). Educational
attainment data is from the Barro-Lee (2013) dataset. Political violence is captured by the total
summed magnitudes of all societal and interstate major episodes of political violence (MEPV) in
a country compiled by Center for Systemic Peace.7 Private credit data has been collected from
Financial Development and Structure Dataset complied by Beck et al. (2000) and revised by
Čihák et al. (2012).
3. Heterogeneous growth trajectories: Some examples
We have earlier illustrated hypothetical examples on possible heterogeneity among
countries in their growth trajectories. In this section, we provide several examples of such
heterogeneity observed in the data in terms of growth rate, BC volatility and LR volatility for
1960-2007 period. Detail information for all sample countries is provided in Appendix A.1. We
also discuss some descriptive statistics at the end of this section.
Namibia vs. Nepal: Both countries had the same average growth rate (about 0.013) and
BC volatility (0.026), but in Namibia (0.019) LR volatility was about twice as large as in Nepal
(0.010).
Columbia vs. Australia: Both countries had almost the same average growth (0.020 vs.
0.021) and BC volatility (0.015 vs. 0.014), but in Columbia LR volatility was much larger than
in Australia (0.013 and 0.008, respectively).
7 MEPV is an annual, cross-national, time-series data on interstate, societal, and communal warfare magnitude
scores (independence, interstate, ethnic, and civil violence and warfare) for all countries. We use the ACTOTAL
series in the dataset. ACTOTAL is calculated as the sum of the magnitude score of episode(s) of: i) international
violence, ii) international warfare, iii) civil violence, iv) civil warfare, v) ethnic violence, and vi) ethnic warfare
involving that state in that year. Each type of violence/warfare is scaled from 1 (lowest) to 10 (highest) for each
MEPV; magnitude scores for multiple MEPV are summed with 0 denoting no episodes.

Argentina vs. Burkina Faso: These two countries also differ only by their LR volatility
(0.022 vs. 0.014); otherwise, they are similar in terms of average growth (about 0.011) and BC
volatility (about 0.044).
Romania vs. Malaysia: Both countries had the same average growth (0.041). But BC
volatility was larger in Malaysia (0.033) than in Romania (0.026), while Romania (0.044) had
more than twice as large LR volatility as Malaysia (0.020).
Japan vs. Cyprus: Both countries had the same average growth (0.043). However,
compared to Cyprus, Japan experienced milder BC volatility (0.033 vs. 0.056) but greater LR
volatility (0.036 vs. 0.020).
Mauritania vs. Fiji: Both countries experienced the same average growth (0.018) but
Mauritania had much greater BC volatility (0.064 vs. 0.043) as well as LR volatility (0.039 vs.
0.017) than Fiji.
Israel vs. Egypt: The two neighbors experienced similar average growth (0.034 vs. 0.037)
but Israel had greater BC volatility (0.053 vs. 0.032) as well as LR volatility (0.036 vs. 0.015)
than Egypt.
There are also examples where similar fluctuations are related to divergent average
growth. For example, growth rate was much higher in Hong Kong (0.048) than in Bangladesh
(0.011) although both countries had the same BC volatility (0.035) and LR volatility (0.019).
Niger and Cyprus can be another likely pair. Both countries had very similar BC volatility (0.054
vs. 0.056) and LR volatility (0.025 vs. 0.020), but Niger economy declined at an average rate of
0.012, while Cyprus grew rapidly at the rate of 0.043. The heterogeneity can also be present
among developed countries. For example, for the 1970-2007 period, average growth rate and BC
volatility in Japan and Austria were the same at 0.024 and 0.014, respectively, but LR volatility
was more than twice in Japan (0.014) than in Austria (0.06).
The above examples illustrate an enormous heterogeneity among countries in their
growth trajectories. More specifically, very dissimilar growth trajectories can lead to the same
average growth. On the other hand, apparently similar growth trajectories can also lead to
different average growth. Figures 1(a)-(j) display growth trajectories of the countries mentioned
above in terms of their long-run growth rate calculated by the low-pass filter.

Average growth rate, BC volatility and LR volatility for the 1960-2007 period in a
sample of 107 countries8 are summarized in Table 1. Countries are classified as high, middle and
low income following the World Bank classification. BC volatility decreases with income
level—it is 0.046 in low income countries compared to 0.036 and 0.024 in middle (upper and
lower middle income combined) and high income countries, respectively. LR volatility is same
in both low and middle income countries (around 0.023) and slightly smaller in high income
countries (0.020). Figures 2(a)-(b) display that both BC and LR volatility decrease with initial
income level. Although BC volatility is larger than LR volatility for all income groups, the ratio
of BC volatility to LR volatility is the largest for low income countries followed by middle and
high income countries (column (4)). The correlation between BC and LR volatility along with
the 95% confidence intervals are reported in column (5). The correlation is 0.61 for all sample
countries; it is the largest for high income countries at 0.84 followed by middle and low income
countries (0.60 and 0.45, respectively). Figure 3 confirms the positive relationship between BC
and LR volatility.
4. Estimation strategies
Our estimation strategy is simple in which long-run growth is regressed on BC volatility
and a set of conditioning variables among which LR volatility is the most important one. The
cross-section specifications are given by:
1 2 ,0i C i i i i iy BCvol LRvol y vα γ γ β ′∆ = + + + + +X δ , ---(1a)
1 ,0 i U i i i iy BCvol y uα γ β ′∆ = + + + +X δ . ---(1b)
Here iy∆ is the average growth rate of real per capita GDP (explained in Section 2), ,0iy is the
log of real per capita GDP in the initial period and X is a set of conditioning variables. Our
attention is on 1Cγ , the (corrected or credible) coefficient on BC volatility ( iBCvol ) in equation
8 These 107 countries are based on the availability of RGDPNA data without any discontinuity. Among these
countries, we consider possible six outliers (based on BC and LR volatility in Appendix A.1)—Equatorial Guinea,
Iran, Rwanda, Gabon, Guinea-Bissau and Syria—but do not exclude them from the sample. The descriptive statistics
and regression results do not qualitatively change if these countries are excluded from the sample.

(1a). We also estimate 1Uγ (the uncorrected coefficient) in equation (1b) without controlling for
LR volatility ( iLRvol ) to compare and contrast with other results in the literature. We show the
direction of bias in 1Uγ at the end of this section.
Choice of controls ( X ) in cross-country growth regressions is a difficult task given that a
large number of variables have been found to be significant in different studies. Some studies
control the variables that are robustly significant in extreme bound analysis (or Bayesian model
averaging). We take a different approach in order to avert the omitted variable bias that involves
controlling only those determinants of growth that also affect BC volatility. Omission of controls
will not cause any bias as long as they are uncorrelated with BC volatility.
The following variables are included in X : (i) investment share in GDP, (ii) (initial)
human capital measured by the year of schooling for aged over 15 years, (iii) population growth
rate, (iv) trade openness measured by the sum of exports and imports as a percentage of GDP, (v)
growth rate of government share in GDP, (vi) terms of trade (ToT) volatility measured as the
standard deviation of the ratio of the export to import prices (as a proxy for external shocks),
(vii) political violence (explained in Section 2), and ix) financial development proxied by the
credit disbursed to the private sector by banks and other financial institutions relative to GDP.
Initial (log) per capita income is also included to account for conditional convergence and the
transitional dynamics so as to avert a positive bias on the coefficient on BC volatility (Martin and
Rogers, 2000, p. 365). The controls (i)-(iii) are common in growth-volatility regressions (for
example, Ramey and Ramey, 1995) but can also be justified by economic reasoning. Investment
is crucial for economic growth but it is also the most volatile component of GDP over business
cycles. Higher population growth can cause economic (and political) instability in a country
unless accompanied by economic growth faster enough to reduce unemployment.9 Higher human
capital, although plays an important role in economic growth, also cause economic and political
instability if left unutilized—the Arab Spring is a recent example (Kuhn, 2012).
The role of openness in economic growth is established both theoretically and empirically
but openness also affects volatility. Using an industry-level panel dataset of manufacturing

Lundblad, 2006).

production and trade, Giovanni and Levchenko (2009) document a positive and economically
significant relationship between trade openness and overall volatility. Mallick (2014) also
observes similar effects using aggregate data at the cross-country level. Kose, Prasad and
Terrones (2006) find out that openness stimulates both growth and volatility.
Growth of the share in government expenditure is intended to account for government
expenditure shocks documented in the Real Business Cycle literature.
Easterly et al. (1993) document that shocks, measured by the change in the ToT,
influence growth directly and also indirectly through policy variables. A negative robust impact
of the change in the ToT on growth volatility is documented by Mallick (2014) and Agénor et al.
(2000). Mendoza (1995) quantifies ToT shocks as accounting for 40%-60% of the observed
variability of GDP at the cross-country level. Koren and Tenreyro (2007) find strong negative
correlations between growth and volatility of country level macro shocks.
Rodrick (1999) show that domestic social conflicts are a key to understanding lack of
persistence in growth performance and growth collapse since the mid-1970s. Social conflicts
interact with external shocks and the domestic institutions of conflict-management. Acemoglu et
al. (2003) argue that bad macroeconomic policies that increase volatility and lower growth are
the results of weak institutions, which is also related to social and political instability.10 Ploeg
and Poelhekke (2009) show that ethnic tensions cause higher volatility and lower growth.11
Financial development is one of the main channels through which volatility affects growth
(Aghion and Banerjee, 2005).
The above list of variables is certainly not a complete one. There may be other variables
that trigger both growth and BC volatility. It is conceivable that many omitted variables are
related to the level of economic development, and therefore controlling for initial income level in
the regression, to a large extent, captures these omitted variables. We additionally include region
dummies (Latin America, Sub-Saharan Africa, Asia Pacific, and Middle East and North Africa)
10 We think that political violence, to a large extent, captures the institutional development. Nonetheless, we also
additionally control for Polity2 to verify robustness, especially for developing countries.
11 In investigating the effect of uncertainty on growth, Baker and Bloom (2013) used natural disasters, terrorist
attacks and unexpected political shocks as instruments of uncertainty measured by the first and second moments of
the stock prices. However, the authors recognize the endogeneity of these shocks in the long run.
13
![Page 14: Business-cycle Volatility and Long-run Growth: How …epu/acegd2014/papers/...However, in the models based on the opportunity cost arguments, the prediction of the effect of business](https://reader033.fdocuments.us/reader033/viewer/2022042114/5e9106816f010029ec32bfb2/html5/thumbnails/14.jpg)
in the regression as some regions are more volatile than others for reasons not discussed above;
these dummies also capture omitted variables in growth regressions (Berg, Ostry and
Zettelmeyer, 2012). Finally, we include dummies for legal origins and landlocked to account for
country fixed effects as well as omitted variables. For example, La Porta et al. (1997; 2008)
document that financial development of a country is greatly influenced by its legal origin.
Financial development data is not available for many developing countries before 1980.
Therefore, in the specification that exclude financial development, legal origin dummies act as
proxies. Growth performance of landlocked countries is dismal and these countries also
experience greater volatility as a result of lack of access to the market (Malik and Temple, 2009).
We construct three cross-sectional datasets for the 1960-2007, 1970-2007 and 1980-2007
periods, respectively, to verify stability of the results across time periods and sample countries
(fewer countries are retained in the 1960-2007 period because of unavailability of data for some
control variables).
The cross-sectional estimation captures the “between” country variations. Panel data
allows a richer investigation by also capturing the “within” country variations. The estimating
equations are written as:
0, 1 , 2 , 1 , , 1 .i C i i i i i iy BCvol LRvol y vτ τ τ τ τ τ τα γ γ β µ η−′∆ = + + + + + + +X δ , ---(2a)
0, 1 , 1 , , 1 , i U i i i i iy BCvol y uτ τ τ τ τ τα γ β µ η−′∆ = + + + + + +X δ . ---(2b)
Here, iµ is the country fixed effects captured by dummies for legal origins and landlocked, τη is
the aggregate time effects captured by time dummies and 0,iy τ is the log of real per capita GDP in
the initial year of each interval. All control variables are lagged by one period ( , 1i τ −X ).
Equation (2a), like equation (1a), will estimate a correlation between BC volatility and
growth. To estimate a casual effect, we need to correct the endogeneity due mainly to reverse
causality from growth to BC volatility. The reverse causality can be both negative and positive.
For example, in Aghion and Banerjee (2005), higher growth leads to volatility. Investment and
borrowing are higher in a boom, leading to higher interest rates. This in turn creates a pecuniary
externality by increasing the debt burden of all entrepreneurs, constraining the growth of
entrepreneurial wealth and investment capacity. At some point, investment capacity falls below
total savings, the economy recedes, and interest rates decrease. The process then reverts to a

boom.12 Lack of growth may also cause political instability that in turn leads to economic
instability. Endogeneity in LR volatility will also bias the coefficient on BC volatility.
Instrumental variable estimation is the solution but it is almost impossible to find exclusion
restrictions for identification in the cross-country growth regressions in the sense that some
exogenous variables affect long-run growth only through BC volatility (unless someone is lucky
enough to find a natural experiment).13 Lagged values are potential candidates for instruments of
contemporaneous values in the panel data. But, as implicit in the literature discussed in
introduction, lagged BC volatility affects growth through cleansing/reallocation effect or
learning-by-doing, so they cannot be valid instruments.14
One way to solve the reverse causality problem is to directly include lagged volatility in
the regression instead of contemporaneous values. This procedure also tests the theoretical
12 However, the authors also argue that this can happen only at certain level of financial development. Credit
constraint is very high in a highly financially underdeveloped country, so that entrepreneurs rely entirely on their
retained earnings for investment. Conversely, in financially developed countries, firms face no credit constraints and
thus can invest up to the expected net present value of their projects. Therefore, financially developed or
underdeveloped countries will not experience volatility; the remaining countries at the intermediate level of financial
development are vulnerable to volatility.
13 Several studies have tried to establish causality from BC volatility to growth using the instrumental variable
regressions. For example, Hnatkovska and Loayza (2005) used the following variables as the instruments of
volatility: the standard deviation of the inflation rate, a measure of real exchange rate misalignment, the standard
deviation of ToT shocks, and the frequency of systematic banking crises. Martin and Rogers (2000) used the
standard deviation of the growth rate of the preceding decade, the initial inflation rate of the decade, the initial level
of GDP per capita and the number of revolutions and coups as instruments for the developing countries. Mobarak
(2005) used diversification as the instrument of volatility. However, exogeneity of these instruments in the long run
can be disputed. Bazzi and Clemens (2013) provide an excellent discussion on the problem of instrument variable
estimation in cross-country growth regressions.
14 A matrix of instruments following the Arellano and Bond (1991) or Blundell and Bond (1998) dynamic panel
estimation using lagged level and differences could also be constructed in a static panel. In addition to the direct
effect of lagged volatility on growth, these instruments also suffer from weak instrument problem because the
requirement for instrumental strength that the variance of the residual must be larger than the variance of the fixed
effect is almost always violated in the cross-country data (see, Bazzi and Clemens, 2013; Newey and Windmeijer,
2009).

predictions of the effect of BC volatility in the previous period on current growth. Provided that
the omitted variable problem is satisfactorily addressed and that BC (and LR) volatility are
calculated using the growth series transformed by one-sided filter using only lag values to avoid
generated reverse causality (discussed in Section 2), the coefficient on BC volatility in the
previous period (interval) will represent a causal effect on current growth. Our identification
approach in this particular context will be more reliable than employing invalid and weak
instruments.15 The following specifications are estimated to obtain a causal effect:
0, 1 , 1 2 , 1 1 , , 1 .i C i i i i i iy BCvol LRvol y vτ τ τ τ τ τ τα γ γ β µ η− − −′∆ = + + + + + + +X δ , ---(3a)
0, 1 , 1 1 , , 1 , i U i i i i iy BCvol y uτ τ τ τ τ τα γ β µ η− −′∆ = + + + + + +X δ . ---(3b)
Since . , 1 . , 1 . , 1( , ) ( , ) ( , ) 0i i i i i iCov v BCvol Cov v LRvol Cov vτ τ τ τ τ τ− − −= = =X , pooled OLS regression
will obtain consistent estimates. The standard errors are clustered at the country level.
Finally, we estimate correlation (both contemporaneous and lagged) at longer horizon
using the historical data constructed by Angus Maddison. We choose the 1875-2010 period in
order to retain a relatively large number of countries in the sample. We first calculate the annual
growth rate by log-differencing per capita real GDP and then construct a 7-year panel data
similar to that constructed in the PWT data. We control only for the (log) initial per capita GDP,
time dummies and dummies for the pre-1914, 1914-1945, 1946-1985; and post-1985 periods,16
as other controls are not available for such a long period.
To know the direction of bias in the coefficient on BC volatility when LR volatility is
incorrectly excluded from the regression, simplify equations (1a)-(1b) excluding the controls:
1 2i C i i iy BCvol LRvol vα γ γ∆ = + + + , ---(4a)
15 The correlation between volatility and growth is arguably no less important than the causal effect. In another
context, Acemoglu, Hassan and Robinson (2011) estimate correlation between the severity of the persecution,
displacement, and mass murder of Jews due to the Holocaust and long-run economic and political outcomes in
Russia because of the lack of exogenous instruments.
16 Romer (2012, p. 192) suggested that macroeconomic history of the USA since the late 1800s consists of four
broad periods: i) before the Great Depression, ii) the Great Depression and World War II, iii) at the end of the World
War II to about mid-1980s, and iv) after mid-1980s. This classification can be readily generalized to other sample
countries except for the first period due to the World War I. Therefore, we modify the first period accordingly.

1 i U i iy BCvol uα γ∆ = + + . ---(4b)
The estimated coefficient on BC volatility in equations (4a) and (4b) can be expressed,
respectively, as:

In the data, corr(BCvol, LRvol) >0. Therefore, the direction of bias in 1̂Uγ depends on the sign of
corr(Δy, LRvol) or, equivalently, the sign of 2γ in equation (4a). If corr(Δy, LRvol) < 0, 1̂Uγ will
be biased downward (i.e., if 1̂Cγ is positive, 1̂Uγ will move towards 0 (or even can become
negative); if 1̂Cγ is negative, 1̂Uγ will increase in absolute value with the negative sign). Similarly,
if corr(Δy, LRvol) > 0, 1̂Uγ will be biased upward (i.e., if 1̂Cγ is positive, 1̂Uγ will be larger; if 1̂Cγ
is negative, 1̂Uγ will move towards 0). Even if corr(Δy, LRvol) = 0, 1̂Uγ will still be biased upward
because of corr(BCvol, LRvol) >0 (in the denominator).
5. Results
We report 1̂Cγ and 1̂Uγ estimated from cross-sectional and panel data for different time
periods and countries. The former represents a credible correlation of BC volatility (or a causal
effect of lagged BC volatility), while the latter represents a biased correlation. We also report 2γ̂ ,
the coefficient on LR volatility, to judge its merit relative to 1̂Cγ in explaining growth, and to
show the direction of bias in 1̂Uγ . This allows both treatment of the issues we intend to address
and a direct comparison with other results in the literature.
5.1 Correlation in cross-sectional data
17
![Page 18: Business-cycle Volatility and Long-run Growth: How …epu/acegd2014/papers/...However, in the models based on the opportunity cost arguments, the prediction of the effect of business](https://reader033.fdocuments.us/reader033/viewer/2022042114/5e9106816f010029ec32bfb2/html5/thumbnails/18.jpg)
The OLS results are summarized in Table 2 for the full (1960-2007), 1960-1980, 1970-
2007 and 1980-2007 periods.17 The odd-numbered columns report 1̂Cγ (and also 2γ̂ ) estimated
from equation (1a). In all periods, 1̂Cγ is close to zero and insignificant (and also no pattern in its
sign) suggesting a lack of correlation between BC volatility and growth. As mentioned earlier,
private credit data are available for a good number of developing countries only after 1980.
Therefore, we have estimated for 1980-2007 period both with and without controlling for private
credit (and Polity2) (columns (5) and (7), respectively). The results are robust in both
specifications.
The even-numbered columns present 1̂Uγ estimated from equation (1b). It is large
negative and statistically significant in 1970-2007 and 1980-2007 periods (columns (6) and (8),
respectively). It is larger in absolute value and significant at higher level if private credit is not
controlled for (column (10)). This result suggests the importance of financial development as an
important channel through which BC volatility interacts with growth.18 With a negative (and
significant) 2γ̂ in equation (1a), 1̂Uγ is biased downward as shown in equations 5(a)-5(b).
Comparing the results from equations (1a) and (1b) for the 1970-2007 period, the coefficient of
BC volatility changes from -0.002 to -0.121. The quantitative implications of this difference is
huge. One standard deviation increase in BC volatility is associated with only 0.003 percentage
point decrease in long-run growth, which is statistically insignificant and also economically
trivial. But if the correlation of LR volatility is removed from the regression, the same increase in
BC volatility would incorrectly be associated with 0.219 percentage point decrease in long-run
growth.

17 The full sample period reduces to 1964-2004 because the first observation is lost after calculating growth rate
from level, and then the next three observations are lost because of employing a one-sided filter with a 3-year
window.
18 If investment is excluded, the coefficient on BC volatility hardly changes suggesting that investment is not an
important channel, which is also consistent with Ramey and Ramey (1995).
18
![Page 19: Business-cycle Volatility and Long-run Growth: How …epu/acegd2014/papers/...However, in the models based on the opportunity cost arguments, the prediction of the effect of business](https://reader033.fdocuments.us/reader033/viewer/2022042114/5e9106816f010029ec32bfb2/html5/thumbnails/19.jpg)
One might suspect that the results from equation (1a) are driven by multicollinearity
between BC and LR volatility. For example, in the 1980-2007 period, 1̂Cγ is 0.053 (positive
though very close to 0 and insignificant), but 1̂Uγ is -0.157 (significant at 10% level) after
removing the correlation of LR volatility. We rule out such a possibility by calculating the
variance inflation factor (VIF) (alternatively, tolerance = 1/VIF). The VIFs (tolerances) of BC
and LR volatility are 2.85 (0.351) and 2.80 (0.357), respectively, which are far less (higher) than
any conventionally considered critical level. Even if only BC and LR volatility are included in
the regression excluding other controls, the VIF (tolerance) is even lower (higher) at 2.31
(0.432).
To further address heterogeneity among countries for reasons other than fluctuations in
the trend growth, we perform disaggregated analysis in several ways. First, we divide the sample
countries into three groups in terms of their intensity of BC volatility: i) least volatile (0-33
percentile), ii) moderately volatile (33-66 percentile), and iii) most volatile (67-100 percentile).
There are 30 countries in each group in the full period, and 36, 35 and 36 countries, respectively,
in both 1970-2007 and 1980-2007 periods. We construct dummies for each volatility group and
interact them with BC volatility. The results are summarized in Table 3. There is no correlation
between BC volatility and growth for any of these three groups, and it is robust across time
periods and sample countries. However, if the correlation of LR volatility is incorrectly removed,
1̂Uγ becomes significantly negative for the most volatile group of countries in both 1970-2007
and 1980-2007 periods.
We now estimate equations (1a)-1(b) disaggregating by income level. The results for
developing (low and middle income combined) countries, summarized in Table 4, are similar to
those for all countries in that there is no correlation between BC volatility and growth. When
developing countries are further disaggregated into three similar groups by their intensity of BC
volatility as the full sample countries, the results are also qualitatively similar (Table 5). There is
also no significant correlation for developed (high income) countries, and the sign of 1̂Cγ changes
across periods (Table 6).
Insert Tables 3-6 here
19
![Page 20: Business-cycle Volatility and Long-run Growth: How …epu/acegd2014/papers/...However, in the models based on the opportunity cost arguments, the prediction of the effect of business](https://reader033.fdocuments.us/reader033/viewer/2022042114/5e9106816f010029ec32bfb2/html5/thumbnails/20.jpg)
The above results indicate an absence of relationship between BC volatility and long-run
growth. However, if the correlation of LR volatility is incorrectly removed, the results are
aligned to the literature to indicate a significant negative relationship especially for developing
countries in the post-1970 period.
5.2 Correlation in cross-sectional data for alternative frequency bands and filtering
Previous estimations are based on the implicit assumption that both developed and
developing countries are characterized by similar cyclical patterns. Although there is a large
literature on business cycles in the context of developed countries, very little is known about
business cycles in developing countries. Agénor McDermott and Prasad (2000) point out that
there are both similarities (procyclical real wages, countercyclical variation in government
expenditures) and differences (countercyclical variation in the velocity of monetary aggregates)
between macroeconomic fluctuations in developing and developed countries. Rand and Tarp
(2002) demonstrate that developing countries differ considerably in terms of the nature and
characteristics of short-run macroeconomic fluctuations. Analyzing a sample of 15 developing
countries (five countries each from sub-Saharan Africa, Latin America, and Asia and North
Africa), the authors document that average lengths of expansion and contraction are 4.8 and 5.2
years, respectively. This suggests that cycles are generally shorter in developing countries. Male
(2009) contrasts this conclusion but stresses that there is heterogeneity at the regional level in
that cycles are shorter in Latin America and longer in Asia.
We now calculate BC and LR volatility using an alternative critical periodicity of 5 years
for developing countries but retain the same critical periodicity for developed countries. The
results, summarized in Appendix A.2, are qualitatively similar to their benchmark counterparts
based on the B-K filter for both the full sample (Panel A) and developing countries (Panel B).
We also calculate BC and LR volatility using the Hodrick Prescott (1997) and Christiano
and Fitzgerald (2003) band-pass filters. These filters extract the cyclical components, and the
trend is retrieved as the residual. Although the H-P filter is optimal for an I(2) process and the C-
F filter is optimal for a random walk process, we nonetheless employ them to verify the
robustness of the results. We use the same window and periodicity in the C-F filter as we have
used in the B-K filter. For the H-P filter, we use a smoothing parameter of 6.25 based on the
recommendation by Ravn and Uhlig (2002, p. 371) that the parameter should be adjusted
20
![Page 21: Business-cycle Volatility and Long-run Growth: How …epu/acegd2014/papers/...However, in the models based on the opportunity cost arguments, the prediction of the effect of business](https://reader033.fdocuments.us/reader033/viewer/2022042114/5e9106816f010029ec32bfb2/html5/thumbnails/21.jpg)
approximately with the fourth power of the frequency change.19 The results using both the H-P
and C-F filters (Appendices A.3 and A.4, respectively) are very similar to the benchmark results.
5.3 Correlation and causation in panel data
Before presenting the results, it is imperative to explain the reasons for constructing a 7-
year panel. A common practice is to take 5-year non-overlapping average of annual growth rate
to calculate its long-run value (some papers also take 10-year average for robustness check).
Using the spectral density, we show in Appendix A.5 that data averaged over 5-year period does
not reweight the variances of the raw series enough across low frequencies, thus data are
contaminated by high frequencies. This contamination decreases substantially in the case of 7-
year averaging. Further improvement is small for averaging over longer horizon, such as 8 or 10
years. Since averaging over longer horizon leaves fewer observations for estimation, we choose
7 years as an optimal compromise. Note that a window of 3 years is also chosen for annual data
in the B-K filter, which is equivalent to averaging over 7 years.
We estimate equations (2a)-3(b) by pooled OLS for both full period (1960-2007) and
1978-2007 sub-period.20 The results for all countries for these two periods are summarized in
Panels A and B in Table 7, respectively. Columns (1)-(4) present the results for the
(contemporaneous) correlation estimated from equations (2a)-(2b); the first two columns control
for private credit (and Polity2), while the last two do not (so the number of observations
increases; and this can also be a test for stability of the results across countries). Columns (5)-(8)
present the effect of lagged BC volatility estimated from equations (3a)-(3b). The coefficient of
BC volatility is insignificant and small in magnitude, thus suggesting a lack of correlation
between BC volatility and growth. There is also no effect of lagged BC volatility on growth as
suggested by its insignificant (and close to zero) coefficient. The results follow similar patterns
for developing countries (Table 8). In both Tables 7 and 8, the correlation becomes significantly
negative and larger in magnitude if LR volatility is incorrectly excluded from the regression. For
developed countries, the results are also similar except that there is a positive correlation of BC
19 STATA also recommends a smoothing parameter of 6.25 for annual data. 20 The effective sample periods 1964-2007 and 1978-2007 cannot be divided into seven equal intervals; for the last
interval, we take average over 9 years (1999-2007).
21
![Page 22: Business-cycle Volatility and Long-run Growth: How …epu/acegd2014/papers/...However, in the models based on the opportunity cost arguments, the prediction of the effect of business](https://reader033.fdocuments.us/reader033/viewer/2022042114/5e9106816f010029ec32bfb2/html5/thumbnails/22.jpg)
volatility in the 1978-2004 period (Table 9). The significance of the correlation does not change
after controlling for LR volatility because of small (and insignificant) value of 2γ̂ (0.10).
Insert Tables 7-9 here
To summarize, the results in the panel data corroborate the main conclusion in the cross-
sectional data. In addition, there is no significant effect of lagged BC volatility on growth. All
the results remain robust (not reported) if the two-sided symmetric filter is used to calculate BC
and LR volatility.
5.4 Correlation in the historical (1878-2010) panel data
We now estimate the relationship using the historical data compiled by Angus Maddison
for the 1875-2010 period.21 This estimation allows us to verify the results from an alternative
dataset and time period. A 7-year panel is constructed similar to the PWT data. There are 28
countries of which 20 are developed by the current income level (A list of countries is provided
in the note for Table 10), and there are 18 observations for each country.22 Due to unavailability
of data for control variables, we control only (log) initial level of GDP, time dummies, and
dummies for major economic episodes: pre-1914, 1914-1945, 1946-1985, and post-1985 periods.
As a result, country fixed effects will be correlated with the omitted variables, so we estimate the
fixed effect regression. We interpret both the coefficients on BC volatility and its lag as
correlation.
Insert Table 10 here
21 Data goes back to earlier period but the number of countries decreases. For example, data is available since 1820
for only 8 countries (Australia, Italy, Denmark, France, Netherlands, Sweden, UK and USA).
22 In the dataset, consecutive values of real per capita GDP since 1875 are available for 28 countries. The actual time
period retained in the analysis is 1879-2010 because the first observation is lost due to calculation of growth rate
from level of GDP, and next three observations are lost due to using the one-sided filter. The time period is then
divided into 18 equal 7-year intervals except the last interval (2004-2010).
22
![Page 23: Business-cycle Volatility and Long-run Growth: How …epu/acegd2014/papers/...However, in the models based on the opportunity cost arguments, the prediction of the effect of business](https://reader033.fdocuments.us/reader033/viewer/2022042114/5e9106816f010029ec32bfb2/html5/thumbnails/23.jpg)
Panels A and B in Table 10 summarize the results for full sample, and 20 developed
countries, respectively. The results are similar in both panels. There is no contemporaneous or
lagged correlation between BC volatility and growth. The correlation becomes negative and
significant, and the lagged correlation becomes positive and significant after incorrectly
removing correlation of LR volatility and its lag, respectively.
5.5 Replication of Ramey and Ramey (1995)
Our final robustness check is to replicate Ramey and Ramey (1995), arguably the most
influential study on the volatility-growth relationship, using their data and controls. We replicate
their basic cross-sectional specification, which is comparable to our specification. Using the
PWT 5.6 data, Ramey and Ramey estimated the relationship for two sets of countries: a full
sample of 92 countries for the 1960-1985 period, and 24 OECD countries for the 1950-1988
period. It is worth mentioning that the PWT data has been revised several times and subsequent
revisions are not strictly comparable. Ponomareva and Katayama (2010) replicated Ramey and
Ramey and found that conclusions based on one version of the PWT may not hold under another
version; however, growth and uncertainty are negatively and significantly related for countries
with the worst data quality.23
Ramey and Ramey calculated growth rate (and volatility) from the “Real GDP per capita,
1985 international prices: Chain Index (RGDPCH)” (their Data Appendix, p. 1150). This is not
the appropriate variable to compare the growth rates over time and across countries; the
appropriate variable is the growth of GDP at constant national prices (also strongly
recommended by Feenstra, Inklaar and Timmer (2013) in the PWT 8.0 user guide, p. 25). GDP
at constant national prices data was not available in the PWT 5.6, so Ramey and Ramey
conducted the best possible exercise given the data. We therefore additionally replicate Ramey
and Ramey using the growth of GDP at constant national prices from the PWT 8.0 for the same

controlling for data quality.

countries and time period. However, this can be done only for their 24 OECD countries as data is
not available for a good number of countries in their full sample.24
Insert Table 11 here
The results are summarized in Table 11. Panel A reports the results for 92 countries for the 1960-
1985 period. In column (1), the coefficient on volatility (standard deviation of the growth rate) in
the specification without any control reported by Ramey and Ramey is reproduced—it is -0.15
with a t-statistic of -2.3 (it becomes -2.6 after correcting heteroskedasticity). However, as we
discuss in detail in Section 6, the standard deviation of the growth rate differ from our measure
of BC volatility (the standard deviation of the business cycles components of growth rate). In the
same specification, the coefficient on BC volatility is very close at -0.16 with a t-statistic of -2.59
(column (2)). When their controls— initial income, average population growth, average
investment share of GDP and initial human capital—are included in the regression, the
coefficient on BC volatility decreases to -0.109 with a t-statistic of -1.636 (which slightly falls
short of 10% level significance) (column (3)). But after controlling for LR volatility, the
coefficient on BC volatility is almost zero (0.006) with a very low t-statistic of 0.066 (column
(4)).
The results for the 24 OECD countries are summarized in Panel B. The coefficient on BC
volatility in the specification with all controls is large negative (-0.41) and significant (t-value of
-2.46), and does not meaningfully change after controlling for LR volatility (columns (3) and (4))
(the coefficient on LR volatility is positive but insignificant). However, when we replicate these
results (with same countries, time period and controls) using the growth of GDP at constant
national prices data from the PWT 8.0 (Panel C), the coefficient on BC volatility is small and
24 In the PWT 8.0, data are not available for the following 9 countries in the Ramey and Ramey sample:
Afghanistan, Algeria, Guyana, Haiti, Myanmar (Burma), Nicaragua, Papua New Guinea, Yugoslavia (country
disintegrated), and Zaire. For Iraq, Sudan and Swaziland, GDP data starts from 1970, and for Liberia from 1964.
Therefore, a total of 13 countries are missing from the sample.

statistically insignificant both without and with controlling for LR volatility, and the sign differs
in the two specifications. These results are perfectly in line with our previous results, and
suggests a lack of relationship between BC volatility and growth.
6. Volatility vs. its persistence
LR volatility is also interpreted as persistence in volatility (Levy and Dezhbakhsh, 2003;
Ascari and Sbordone, 2014). In the following, we compare the relative importance of BC
volatility and persistence in volatility in explaining long-run growth.
We have found that there is no correlation between BC volatility and growth, and no
effect of lagged BC volatility on growth. But the correlation becomes significant and stronger if
LR volatility is incorrectly excluded from regression. Moreover, the results show a negative and
significant correlation between LR volatility and growth, especially for developing countries and
in the post-1970 period. On the other hand, the correlation is positive in the 1960-1980 period
but not robust across country income groups. It is positive for developed countries in the post-
1970 period but not robust to estimation methods. The correlation is weakly negative in the
Angus Madison panel data (Table 10). The effect of lagged LR volatility is positive for
developed countries (Table 9, Panel B and Table 10). These findings signify the importance of
LR volatility in explaining growth. They also imply that if LR volatility is omitted from the
regression, its effect, to a large extent, will be reflected in the coefficient of BC volatility.
Several studies (for example, Ramey and Ramey, 1995) use standard deviation of
(unfiltered or raw) growth rate as a proxy for BC volatility. This measure is based on the
assumption of a constant trend, while BC volatility calculated as the standard deviation of the
cyclical components of growth assumes a time varying trend. As shown in introduction, total
variance of growth rate is sum of the variances of its cyclical and long-run components.
Therefore, volatility measured as the standard deviation of growth rate will capture the combined
effects of both BC and LR volatility. In other words, both the standard deviation of the cyclical
components of growth (in misspecified regression that excludes LR volatility) and that of the
(unfiltered or raw) growth will capture the effect of LR volatility.
Insert Table 12 here
25
![Page 26: Business-cycle Volatility and Long-run Growth: How …epu/acegd2014/papers/...However, in the models based on the opportunity cost arguments, the prediction of the effect of business](https://reader033.fdocuments.us/reader033/viewer/2022042114/5e9106816f010029ec32bfb2/html5/thumbnails/26.jpg)
To verify the above argument, we estimate correlation (and effect) of total volatility
defined as the standard deviation of (unfiltered or raw) growth rate. The results for some selected
specifications based on the significance of 2γ̂ (coefficient on LR volatility) and/or 1̂Uγ
(uncorrected coefficient on BC volatility) are presented in Table 12. Consider the cross-sectional
results for 1970-2007 period presented in columns (1)-(3) in Panel A. The first two columns
reproduce the results from columns (5) and (6) in Table 2, respectively. In column (3) we add the
result for total volatility (based on the same specification). The coefficient on total volatility is
negative and significant. Quantifying the result, one standard deviation increase in total volatility
is associated with 0.263 percentage point decrease in growth. On the other hand, 1̂Cγ (corrected
coefficient on BC volatility) was insignificant but 2γ̂ was negative and significant. The latter
result can be quantified as 0.297 percentage point decrease in growth for one standard deviation
increase in LR volatility. But 1̂Uγ became negative and significant after omitting LR volatility in
the regression—it implied that one standard deviation increase in BC volatility was incorrectly
associated with 0.219 percentage point decrease in growth. These results support our argument
that the contribution of LR volatility is misconstrued as the contribution of total volatility or that
of BC volatility because of misspecification.
To summarize, it is not BC volatility but persistence in volatility that is associated with
growth, and the association differs across time periods and country groups.
7. Relating the contribution in the literature
Our paper is situated in a large body of literature on the volatility-growth relationship but
can be distinguished by its contribution in accounting for the persistence in growth volatility.
The issue of persistent fluctuations has been raised in the cross-country macroeconomic literature
in several contexts. In the following, we compare and contrast our contributions in this literature.
Fatás (2000a, 2000b) document a strong positive correlation between long-run growth
rates and persistence of output (not growth) fluctuations in a cross section of countries. The
results suggest that volatility of the permanent component of output is larger for countries with
high growth rates. In contrast, we deal with a different question regarding growth volatility and
document that the relationship between growth and persistence in growth volatility differ across
time periods and country groups.
26
![Page 27: Business-cycle Volatility and Long-run Growth: How …epu/acegd2014/papers/...However, in the models based on the opportunity cost arguments, the prediction of the effect of business](https://reader033.fdocuments.us/reader033/viewer/2022042114/5e9106816f010029ec32bfb2/html5/thumbnails/27.jpg)
Some studies have distinguished volatility between its unexpected (uncertain) and
expected components. It is imperative to distinguish between uncertainty in, and volatility of,
growth. Uncertainty accounts for only the unpredicted component of growth, while volatility
accounts for both predicted and unpredicted components (Wolf, 2005).25 Uncertainty is usually
calculated as the residual of a forecasting equation where GDP growth is regressed on its own
lags and linear (and quadratic) trends (see, Ramey and Ramey, 1995; Fatás, 2002; Rafferty,
2005). Although introducing the trends removes low frequency movements from the data and
therefore is comparable to the band-pass filtered growth, BC volatility in our paper is a measure
of ex post realized volatility as opposed to uncertainty. Ramey and Ramey (1995) and Rafferty
(2005) included in the regression both unexpected and expected volatility, where the latter was
calculated as the standard deviation of the fitted value of growth rate. Our measure of LR
volatility is different from the expected volatility in the same way as low-pass filtering differs
from fitting. The aim of low-pass filtering is to retain slow-moving values, whereas fitting
concentrates on achieving as close a match of data values as possible. Furthermore, filtering,
unlike fitting, does not involve use of an explicit function form. These differences are also
manifest in the differences in results discussed below.
Ramey and Ramey (1995) found that both the coefficients on unexpected and expected
volatility were insignificant (negative and a low t-statistic) in a sample of 92 countries. On the
other hand, in a sub-sample of OECD countries, the coefficient on unexpected volatility was
negative and highly significant, and the coefficient on expected volatility was positive and
significant. Kormendi and Meguire (1984) earlier found that standard deviation of monetary
shocks has a significant negative effect and standard deviation of growth rate has a significant
positive effect on growth. Ramey and Ramey (1995) conjectured that the standard deviation of
monetary shocks may be correlated with unexpected volatility. Thus, the positive effect of the
standard deviation of output in Kormendi and Meguire may be capturing the effect of predictable
movements in growth, similar to their expected volatility. On the other hand, we find a lack of
correlation between BC volatility and growth, and a negative and significant correlation between
LR volatility and growth, especially for developing countries in the post-1970 period. Similarly,
using the Angus Maddison historical data for 18 developed countries for the 1880-1990 period,
Rafferty (2005) found that unexpected volatility reduces, and expected volatility increases, long-
25 Bloom (2014) discusses different measures of uncertainty employed in the literature.

run growth. Using the same data, we instead find no association (and effect) of BC volatility, and
a weak negative association of LR volatility with growth.
Hnatkovska and Loayza (2005) distinguish between “regular” and “crisis” volatility and
show that only “crisis” volatility is statistically significant for explaining growth when both types
of volatility are included in the regression. The authors define “crisis” volatility as the portion of
the standard deviation of GDP growth that corresponds to downward deviations below a certain
threshold. They set the threshold equal to one standard deviation of the world distribution of
overall volatility measures. Regular volatility, on the other hand, is defined as the portion of the
standard deviation of GDP growth corresponding to deviations that fall within the threshold.
Their distinction of the two types of volatility can be compared to our disaggregation of
countries in terms of their intensity of BC volatility. But our contribution lies in accounting for
LR volatility for which Hnatkovska and Loayza have no counterpart.
Aguiar and Gopinath (2007) point out that shocks to trend growth can be the primary
source of fluctuations in the emerging market economies as opposed to transitory fluctuations
around the trend. The authors document that these economies on average have a business cycle
twice as volatile as that of their developed counterparts. They measured business cycle by
volatility of the H-P band-passed filtered log output, and volatility of the first difference of
unfiltered log output, which corresponds to our measure total volatility in Section 6. They also
document that the first-order autocorrelation of unfiltered output growth is twice as large,
suggesting greater persistence in business cycles in emerging economies (their Table 1, p. 74).
Although our study differs from theirs in regard to the research question, we document in Table
1 that both BC and LR volatility decrease with income level, but so does their ratio. This implies
that LR volatility relative to BC volatility is also larger in developed than in developing
countries.
Our paper is also situated in a burgeoning literature on growth spells first pioneered by
Pritchett (2000).26 Pritchett pointed out heterogeneity among countries in terms of instability in
growth rates over time. Country experiences differ enormously by steady growth, rapid growth
followed by stagnation, rapid growth followed by decline or even catastrophic falls, continuous
26 Some recent papers have attempted to explore the determinants of the growth spells (for example, Berg, Ostry and
Zettelmeyer, 2012; Bluhm, Crombrugghe and Szirmai, 2014).

stagnation, or steady decline. He cautioned that econometric growth literature using the panel
nature of data may be uninformative to account for the heterogeneity. Our motivation and
approach to account for heterogeneity address this concern.
8. Concluding remarks
This paper finds that at the cross-country level there is no relationship between BC
volatility and long-run growth. The main departure from the extant empirical literature is in
accounting for fluctuations in the trend growth that we refer to as LR volatility. However, a
significant negative relationship can be found, especially for developing countries, if LR
volatility is incorrectly excluded from regression, which is consistent with the findings in the
literature. Our measure of LR volatility—standard deviation of the low-pass filtered growth
rate—also represents persistence in volatility. We find that persistence in volatility is negatively
associated with growth, especially for developing countries in the post-1970 period. We also test
the theoretical prediction of the effect of BC volatility in previous period on current growth but
do not find any such effect. There might be an asymmetry in the effect of BC volatility in that
volatility in expansionary and contractionary phases may have differential impacts on growth,
which can be an interesting topic to explore further.
Our results have important implications for stabilization policies in light of the recent
global financial crises. The large decline in output and very slow recovery after the 2008
recession compared to the previous recessions suggest a reduction in the trend growth rate in
many developed countries. But such contractions are more frequent in developing countries.
Causes and remedies of such fluctuations are largely unknown and require further investigation.
Our finding of lack of (or weak) correlation between BC volatility and growth does not
necessarily imply irrelevance of stabilizing business cycles since cyclical fluctuations may affect
heterogeneous agents differently that is not evident at the aggregate data.27 Our results have also
27 Lucas (1987) documented that the welfare effects of eliminating business cycle are very small, well below 1% of
national income. Krusell and Smith (1999) investigate these effects in a model with substantial consumer
heterogeneity that arises from uninsurable and idiosyncratic uncertainty in preferences and employment status. The
results suggested a welfare loss larger than Lucas (1987), but still very small. However, this model is based on the
assumption that individual shocks are unaffected by the removal of the cycles. If this assumption is relaxed, the

A.5: Comparison of spectral densities
The spectral density for averaging over T years is given by:
( ) ( ) ( )21/ 1 cos / 1 cosT Tω ω− − , where ω is the frequency ranging between 0 and π (for
derivation, see Sargent, 1987, p. 275). The spectral densities for T = 5, 7, 8 and 10 are displayed
in Appendix Figure A.1. They are normalized using appropriate scalars so that the area under the
curves are equal. A vertical line is drawn at 0.786 to mark the critical frequency that separates
the long-run from cyclical components. Note that the periodicity (p) and frequency are inversely
related by the formula: 2 /p π ω= . For a critical periodicity of 8 years, the corresponding critical
frequency is 0.786. It can be seen from the graph that 5-year averaging does not reweight the
variances of the raw series enough across low frequencies, thus the transformed data are more
likely to be contaminated by high frequencies. The area under the spectral density to the right of
the vertical line is 14% of the total area for 5-year averaging. The area substantially reduces
9.3% for 7-year averaging; it remains the same for 8-year averaging and reduces only to 8.8% for
10-year averaging.
